摘　　要：以双离合自动变速器中齿轮为研究对象,利用KISSsoft软件,依据ISO/TR 15144-1:2010中方法 A计算同一齿轮副在不同微观修形参数下对应的最小膜厚比,评价其抗微点蚀能力。对不同修形方案的齿轮进行加载试验,通过对试验后齿轮齿面微点蚀状态的观察和检测证明,适当地优化齿轮微观修形参数增加最小膜厚比能有效改善齿面微点蚀现象。A gear pair in a Dual Clutch Transmission was researched. Using the KISSsoft software ,the minimum specific lubricant film thickness corresponding to different micro modification parameters of the same gear pair was calculated based on the method A in the ISO/TR 15144-1：2010 ,which was used to evaluate its micropitting resistance. Gear loading tests were carried out on different micro modification parameters ,by observing and inspecting the tooth surface after the tests , proved that the appropriate optimized micro modification parameters and the increased minimum specific lubricant film thickness can improve the micropitting phenomenon effectively.
